Cuttings of Yours Truly and Easham cultivars of zonal geraniums (Pelargonium × hortorum) and Dark Pink, a cultivar of ivy geranium (Pelargonium peltatum), were rooted in peat and perlite (1:1, v/v) that had been treated with six commercially available fungicides alone and in combinations and compared with cuttings rooted in untreated mix. In general, the fungicides tested neither enhanced nor inhibited root initiation. Caution is urged in extrapolating these results to other media, plant materials, seedling production, other fungicides, and different timing of application.
